Platelet-Activating Factor Acetylhydrolase (PAFAH) is a monocyte-derived phospholipase A2 that catalyzes the hydrolysis of platelet-activating factor (PAF) and has been implicated in atherosclerosis. Although PAF and other proinflammatory stimuli are postulated to induce the enzyme, mechanisms controlling PAFAH expression are largely unknown at present. We have shown that PAFAH induction in monocytes is increased in response to oxidized phospholipids. The PAFAH 5' flanking region has at least 10 putative Stat elements, and IL-6 has been shown to be downstream from the prostaglandin receptor, EP2, which has been shown to bind oxidized phospholipids, prompting the hypothesis that Stat proteins might regulate …
